adventures in chemical ecology, mass spectrometry and other cool stuff

One of the engineers came to me today with the print head of a 3D printer that had become blocked with the polylactic acid [PLA] the printer dispenses. He wanted to know if U had any solvents to dissolve the blockage. Time to roll out some dichloromethane and a little bit of tetrahydrofuran! They’ll dissolve most plastics: THF will even dissolve teflon!
